Ok (especially the mast & boom design), but I think that if "close the doors in event of a storm" isn't followed there is no possible safeguarding that the manufacturer could have implemented - short of just not offering beaches on yachts which all customers demand. You can't have several giant open holes in the hull & offer the same safety regardless of if they are open or in a closed bolted position.

If a ferry went down bcs the loading gates were open in rough sea the reason seems clear.

Also for just about any 10+ million moneys yacht that got destroyed there are always unbelievably stupid reasons. Eg a modern 60+ ft yacht beaching on an island at cruise speed is ... just stupid.

Same with this ones beach club hatches - maybe the passengers demanded they are open when they wake up & the wage crew had to comply.

As for the keel not being in a lowered position that is just extra stupid, and not just bcs of the weather warnings flashing. Sailing boats need it, and dynamic ones (usually more for performance than comfort) can offer more or less stability by design. And at that depth (or just the fact they were anchored) the keel being up just doesn't make sense beyond an active decision that 'its fine' by the crew.
